She's barely 49% confident. I understand she doesn't want to enjoy a demo effect in a moving vehicle with 2 guests but it's a bit disturbing to see her hands constantly willing to grab the wheel.
This is so clearly a fake demonstration. Watch the way the "automation" follows the probe car. It's so clearly leading it on and the woman is just going through an act.
In another video a different pair of accompanying passengers record a similar sequence of events, so the demonstration itself is probably scripted and rehearsed. But I wouldn't rule out that there is an actual piece of software working under these (controlled) conditions.
